Keyword Density Checker
Instantly analyze keyword frequency and density in your content. Works entirely in your browser — no data sent to any server.
How to Use
- 1
Paste your content
Copy any blog post, landing page copy, or article and paste it into the text area. The longer the content, the more accurate the analysis.
- 2
Add a focus keyword (optional)
Enter the primary keyword or phrase you're targeting. You'll see its exact count and density highlighted separately from the overall analysis.
- 3
Click Analyze
The tool instantly calculates word count, character count, and keyword frequency — entirely in your browser. Nothing is sent to a server.
- 4
Review the results
Switch between "Single Keywords" and "2-Word Phrases" tabs to spot over-used terms. Check the density status: aim for Optimal (0.5–2.5%) on your focus keyword.
- 5
Adjust your content
Edit your text, paste it back in, and re-analyze. Repeat until your focus keyword is in the optimal range and there are no overstuffed terms.
Why It Matters
Keyword density tells you how often a target keyword appears relative to the total word count. While Google no longer uses a fixed density threshold, content that repeats a keyword too rarely signals weak topic relevance — and content that repeats it too often (keyword stuffing) can trigger a manual or algorithmic penalty. The generally accepted sweet spot is 0.5–2.5% for your primary keyword and naturally distributed usage of related terms (LSI keywords). For long-tail keywords — phrases of three or more words — density matters less than natural placement in your title, first paragraph, headings, and meta description. This tool helps you verify you've hit that balance before publishing, catching both under-use and over-use before they hurt your rankings.
